Nah, it's D) Manhattan if you're thinking about grid paths!

Wait, is it really just a straight line? Sounds too simple.

I feel like cosine is more about angles, so it can't be the right answer. I'm leaning towards Euclidean too.

Euclidean sounds right to me for straight lines, but I might be mixing it up with something else.

I remember practicing a question like this, and I think Manhattan distance is more about grid-like paths, not straight lines.

I think the straight line metric is the Euclidean distance, but I'm not entirely sure.
